Abstract
屋外使用が可能で、指向性が無く、小型で簡便に使用でき、かつ30m/secぐらいまでの風速を測れる風速計が求められている。
【解決手段】 天頂部が塞がっている底のない外径2cm程で、高さ5cm程の円筒状の外筒の中に、天頂部と底部が塞がってない高さ約5cmの少し細めの円筒状の内筒を同軸的に挿入し、内筒の天頂部は外筒の天頂部内側より少し下げて1mmほど隙間が開けてあり、内筒の下端は外筒の下端より2mmほど下に出してあり、外筒内面と内筒外面との間は0.5mmの均一な間隔が取ってあり、外筒の内側には発熱体と温度センサーが一体化された空気流検知器が設置してある構成からなる風速計。

Claims (3)
- 本装置は、天頂部が塞がっている底のない外径2cm程で、高さ5cm程の円筒状の外筒の中に、天頂部と底部が塞がってない高さ約5cmの少し細めの円筒状の内筒が同軸的に挿入されており、内筒の天頂部は外筒の天頂部内側より少し下げて1mmほど隙間が開けてあり、内筒の下端は外筒の下端より0.5〜2mm下に出してあり、外筒内面と内筒外面との間は0.5〜1.5mmの均一な間隔が取ってあり、外筒の内側には発熱体と温度センサーが一体化された空気流検知器が設置してあり、発熱体は昇温してあるが、外筒及び内筒の底部に風が吹き付けるとき、内筒内に生じる圧力と内筒と外筒の間の空間に生じる圧力に差ができるため、装置内部に空気の流れが起こり、発熱体から熱を奪うので、その発熱体の温度変化を風速の関数としてとらえ、風速を測ることを特徴とする風速計。
- 空気流検知器の発熱体としては電気抵抗を使用し、一定電流を流して昇温しておくことを特徴とする請求項1記載の風速計。
- 空気流検知器としては抵抗値と温度に相関のある電気抵抗体の発熱機能と温度検知機能を利用したものを使用し、電流を流して一定温度にしておくための電流変化を風速の関数としてとらえることを特徴とする請求項1記載の風速計。
